Iam trying to enable the Rating settings programmatically but it seems not working . Iam not getting any error but it dont update the list with new columns LikeCount and LikedBy. I dont want to use PnP samples . Here is my code:

 private void SetProperty(ClientContext ctx, string listname, VotingExperience experience)
    {
       Web rootWeb = ctx.Site.RootWeb;
       List list = rootWeb.Lists.GetByTitle(listname);

        try
        {
            list.Context.Load(list.RootFolder, p => p.Properties);
            list.Context.ExecuteQueryRetry();

       list.RootFolder.Properties["Ratings_VotingExperience"] = experience.ToString();
            list.RootFolder.Update();
            list.Context.ExecuteQueryRetry();

       }
        catch (Exception ex)
        {
            //
        }
    }

Accessing :

SetRating(ctx, Lists.title, VotingExperience.Likes);

Is it correct way of doing ?? Anyone has experienced?

It seems you are trying with a invalid property name. Instead of Ratings_VotingExperience use Ratings_x005f_VotingExperience.

list.RootFolder.Properties["Ratings_x005f_VotingExperience"] = "Likes";

So question is: Where did I get that? In the following end-point:

/_api/Web/GetFolderByServerRelativeUrl('/Lists/{ListName}')/Properties

I have sent a GET request to the above URL and it returned me something like Ratings_x005f_VotingExperience.

Update

It's true above thing does not work! So I had a little R&D and made it working. Basically we need to add two site columns in list to make Rating thing working. I got the idea from Rating Settings itself.

enter image description here

Site columns are:

  • LikesCount which GUID ID is 6e4d832b-f610-41a8-b3e0-239608efda41
  • LikedBy which GUID ID is 2cdcd5eb-846d-4f4d-9aaf-73e8e73c7312

PS: These Guids are fixed

So I added these columns using below code and enabled Rating Settings

using(ClientContext clientContext = new ClientContext(targetSite)) {
    clientContext.Credentials = onlineCredentials;
    Web web = clientContext.Web;
    List list = web.Lists.GetByTitle("List Name");
    clientContext.Load(list);
    clientContext.ExecuteQuery();

    var likeCount = web.AvailableFields.GetById(new Guid("6e4d832b-f610-41a8-b3e0-239608efda41"));
    var likedBy = web.AvailableFields.GetById(new Guid("2cdcd5eb-846d-4f4d-9aaf-73e8e73c7312"));

    clientContext.Load(likeCount, p => p.SchemaXmlWithResourceTokens, p => p.Id, p => p.InternalName, p => p.StaticName);
    clientContext.Load(likedBy, p => p.SchemaXmlWithResourceTokens, p => p.Id, p => p.InternalName, p => p.StaticName);
    clientContext.ExecuteQuery();

    list.Fields.AddFieldAsXml(likeCount.SchemaXmlWithResourceTokens, true, AddFieldOptions.AddFieldInternalNameHint | AddFieldOptions.AddToAllContentTypes);
    list.Fields.AddFieldAsXml(likedBy.SchemaXmlWithResourceTokens, false, AddFieldOptions.AddFieldInternalNameHint | AddFieldOptions.AddToAllContentTypes);

    list.Update();
    clientContext.ExecuteQuery();
}

Above code will enable like/unlike. For other things, we have enable those also. Find here

private readonly Guid RatingsFieldGuid_AverageRating = new Guid("5a14d1ab-1513-48c7-97b3-657a5ba6c742");
private readonly Guid RatingsFieldGuid_RatingCount = new Guid("b1996002-9167-45e5-a4df-b2c41c6723c7");
private readonly Guid RatingsFieldGuid_RatedBy = new Guid("4D64B067-08C3-43DC-A87B-8B8E01673313");
private readonly Guid RatingsFieldGuid_Ratings = new Guid("434F51FB-FFD2-4A0E-A03B-CA3131AC67BA");
